Kovar alloy 4j29

4J29 amavuta azwi kandi nka Kovar alloy. Amavuta afite coefficente yo kwaguka kumurongo isa niy'ikirahure gikomeye cya borosilique kuri 20 ~ 450 ℃, ahantu harehare cyane kuri Curie hamwe nubushyuhe buke bwa microstructure. Filime ya oxyde ya alide ni nyinshi kandi irashobora kwinjizwa neza nikirahure. Kandi ntishobora gukorana na mercure, ikwiriye gukoreshwa mubikoresho birimo gusohora mercure. Nibikoresho nyamukuru bifunga ibikoresho byububiko bwamashanyarazi. Ikoreshwa mugukora Fe-Ni-Co alloy strip, akabari, isahani hamwe numuyoboro hamwe nikirahure gikomeye / ceramic ihuza kashe, ahanini ikoreshwa mubikoresho bya elegitoroniki ya vacuum, electronics electronique nizindi nganda.
4J29 Incamake yo gusaba hamwe nibisabwa bidasanzwe
Amavuta ni Fe-Ni-Co isanzwe ikirahure gifunga ikirahuri gikunze gukoreshwa kwisi. Yakoreshejwe ninganda zindege igihe kinini kandi imikorere yayo irahagaze. Ikoreshwa cyane cyane mukirahuri cyikirahure cyibikoresho byumuyagankuba nkumuyoboro w’ibyuka bihumanya ikirere, umuyoboro wa oscillation, umuyoboro w’umuriro, magnetron, transistor, icyuma gifunga, relay, umurongo uhuza imirongo, chassis, shell, bracket, nibindi. Mubisabwa, the kwaguka coefficient yikirahuri cyatoranijwe hamwe nuruvange bigomba guhuzwa. Ubushyuhe buke bwimitsi irageragezwa cyane ukurikije ubushyuhe bwo gukoresha. Uburyo bwiza bwo kuvura ubushyuhe bugomba gukorwa mubikorwa byo gutunganya kugirango ibikoresho bigire ishusho nziza yimbitse. Mugihe ukoresheje ibikoresho byo guhimba, umwuka wacyo ugomba kugenzurwa cyane.
Covar alloy kubera ibirimo cobalt, ibicuruzwa birwanya kwambara.
Irashobora gufungwa byoroshye hamwe nikirahuri cya molybdenum, kandi ubuso rusange bwakazi bukenera isahani.
4J29 Imiterere:
Amavuta afite imbeho nziza kandi ashyushye, kandi irashobora gukorwa muburyo butandukanye bwibice. Nyamara, gushyushya ikirere kirimo sulfuru bigomba kwirindwa. Mugihe gikonje, mugihe ubukonje bukabije bwumurongo burenze 70%, anisotropy ya plastike izaterwa nyuma yo gufatana. Iyo igipimo cyimbeho ikonje kiri hagati ya 10% ~ 15%, ingano zizakura vuba nyuma yo gufatana, kandi anisotropiya ya plastike ya aliyumu nayo izakorwa. Anisotropy ya plastike ni ntoya mugihe igipimo cya nyuma cyingutu ari 60% ~ 65% naho ingano ni 7 ~ 8.5.
4J29 Ibikoresho byo gusudira:
Amavuta ashobora gusudwa n'umuringa, ibyuma, nikel nibindi byuma ukoresheje brazing, gusudira fusion, gusudira kurwanya, nibindi. gusudira. Mbere yuko umusemburo ufungwa ikirahure, ugomba gusukurwa, ugakurikirwa no kuvura ubushyuhe bwo hejuru bwa hydrogène no kuvura mbere ya okiside.
4J29 Uburyo bwo gutunganya isura: Kuvura hejuru birashobora kuba umusenyi, gutonesha, gutoragura.
Ibice bimaze gufungwa nikirahure, firime ya oxyde yakozwe mugihe cyo gufunga igomba gukurwaho kugirango byoroshye gusudira. Ibice birashobora gushyuha kugeza kuri 70 ℃ mumuti wamazi wa 10% hydrochloric aside + 10% acide ya nitric, hanyuma ugashiramo 2 ~ 5min.
Amavuta afite imikorere myiza ya electroplating, kandi hejuru irashobora kuba yometseho zahabu, ifeza, nikel, chromium nibindi byuma. Mu rwego rwo koroshya gusudira cyangwa gushyushya guhuza ibice, akenshi usanga ushyizwemo umuringa, nikel, zahabu na tini. Kugirango tunonosore imiyoboro yumuvuduko mwinshi kandi ugabanye guhangana kugirango hamenyekane ibintu bisanzwe biranga imyuka ya cathode, zahabu na feza bikunze gushyirwaho. Kugirango urusheho kunanirwa kwangirika kwigikoresho, nikel cyangwa zahabu birashobora gushyirwaho.
4J29 Gukata no gusya imikorere:
Ibiranga gukata biranga ibimera bisa nibyuma bya austenitis. Gutunganya ukoresheje ibyuma byihuta cyangwa ibikoresho bya karbide, gutunganya umuvuduko muke. Coolant irashobora gukoreshwa mugihe ukata. Amavuta afite imikorere myiza yo gusya.
4J29 Ibisobanuro nyamukuru:
4J29 umuyoboro udafite ikidodo, icyuma cya 4J29, icyuma cya 4J29, ibyuma 4J29, kwibagirwa 4J29, impeta ya 4J29, umuyoboro wogoswe, 4J29, icyuma cya 4J29, umurongo wa 4J29, insinga 4J29 hamwe n’ibikoresho byo gusudira, 4J29 cake yuzuye, 4J29 hex akabari, umutwe wa 4J29, inkokora 4J29, 4J29 tee, ibice 4J29 4J29, 4J29 ibimera n'imbuto, 4J29 bifunga, n'ibindi.
